To all whom it may concern.-

Be it known that I, BRADFORD H. TRIPP, a citizen of the United States, residin at Remsen, in the county of Plymouth an State of Iowa, have invented a new and useful Corn- Harvester, of which the following is a specification.

This invention relates to corn gathering-or harvesting devices of the class which are equipped with means for snapping the ears from the stalks, means for conveyin the ears to a husking device, and means for e riving the ears of the husks, and for finall elivering the ears into a receptacle.

The invention has for its object to provide a machine of the class referred to which shall possess superior advantages in point of simplicity, durability, and general efliciency.

With these and other ends in view, whichwill readily appear as the nature of the invention is better understood, the same consists in the improved construction and novel arrangement and combination of parts, which will be hereinafter fully described, and particularly pointed out in the claims.

In the accompanying drawings has been illustrated a simple and preferred form of embodiment of the invention, it being, however, understood that no limitation is necessarily made to the precise structural features therein exhibited, but that the right is reserved to any changes, alterations, and modifications to which recourse may be had within the scope of the invention and without departing from the spirit or sacrificing the efiiciency of the same.

In said drawings, Figure 1 is a top plan view of a corn-harvester constructed in accordance with the principles of the invention. Fig. 2 is a sectional elevation of the same. Fig. 3 is a sectional elevation taken on'the line 3 3 of Fig. 1. Fig. 4 is a sectional view taken on the line 4 4 in Fig. 1. F i 5 is a plan View showing the snapping-rollers and the supporting and driving means for the same. Fig. 6 is a sectional detail view taken through the elevating and husking device and exhibiting a pair of the huskin -rollers. Corresponding parts in the severzil figures are indicated by like characters of reference.

The main frame of the improved machine is composed of the outer and inner side beams 1 2, which are suitably connected by means of cross-pieces 3 3, which are laterally extendand supporting-wheels 9, said truck being connected with the front cross-piece 4 by means of a swivel or king bolt 10-. The framepieces 1 2 support upri hts 1 1,.the upper ends of which are connected by cap-beams 12 and 12 which are extended laterally above the extensions of the cross-pieces 3 3 and which assist'in supporting the gathering frame F.

The gathering-frame comprises the lower 'corn guides 14 15 and the upper corn-guides 16 17, which latter, in addition to being supported by the ca -beams or cross-pieces 12 12*, are supported of a yoke 18, connected with an upright 19, rising' from the frame-piece 2. The front end of the lower inner corn-guide 15 is supported by one of the cross-bars 3 of the frame. The lower corn-guides 14 and 15 are provided at their front ends with forwardly-extending gathering-fingers 20 for the purpose of picking up down corn and guiding it between the conveying members, which will be presently described.

The lower cornuides 14 15 are provided upon their inner si es with recesses 21 for the accommodation of the snapping-rolls 22, the shafts of which are journaled at their front ends in said corn-guides and at their rear ends in one of the cross-pieces 3.

The outer upper corn-guide 16 is provided near its front and rear ends with slots 24, affording bearings for laterally-slidable boxes 25. Pivotally mounted upon the lower outer corn-guide 14, near the front and rear ends of the latter, are arms 23, the free ends of which have boxes or bearings 26 26, in which are j ournaled the lower ends of shafts 27, the upper ends of which are journaled in the boxes25. The shafts 27 carry the drums or cylinders 28. Springs 29 are suitably arranged to force the several shaft-supports in an inward direction. The inner corn-guides 15 17 are provided with bearings for shafts 30, carrying drums or cylinders 31. The drums 28 and 31, which are approximately vertically disposed, serve to support endless and reinforced by means aprons 32 33, each equipped with toothed slats 34 34 and coperating to constitute an endless carrier. It will be seen that the shafts 27, carrying the drums 28, which support the outer apron 32, arecapable of being forced in t nsion of the s rings 29, thus permitting the carrier to yiel to the pressure of material assing between the members thereof.

The transporting-wheel or traction-wheel 7 carries a sprocket-wheel 35, which is connected by a chain 36 .with a sprocket-wheel 37- upon a counter-shaft 38. The latter carries a bevel-gear 39, meshing with a bevelgear 40, upon the lower 'end of the rear drumsupporting shaft 30, which is thus driven. The upper end of said rear shaft 30 carries-a sprocket-wheel 41, which is connected by a chain 42-with a sprocket-wheel 43 upon a stub-shaft 44, which is mounted in the box 25, which supports the upper end of the-rear shaft 27; Said rear shaft-27 carries a pinion 45, meshing with a pinion 46 upon the stubshaft 44. ,A. springactuated chrin-tightener 47 is providedto keep the chain'42 taut. It will be seen that by this mechanism motion is transmitted ,the proper direction from the rear shaft 30 to;the rear shaft 27 without interfering with'theilexibility of the supporting means for said shaft. 1 a

The outer transporting-wheel 6 carries a sprocket-wheel 46, which is connected by a chain 47' with the sprocketwheel 48' upon a counter-shaft 49, having a,. l evel-pinion 50, meshin with a bevelpinio 1' i, 51 upon the shaft 0 one of the snapping-rolls, which is thereby driven. The shafts of the snappingrolls are also provided with intermeshin'g pinions 52, whereby both of said rolls are driven in the roper direction.

Un er the rear or discharge ends of the aprons 32 33 is disposed a chute 53, dis- 0 argin into the lower end of the trough 54 of the e evator 55. Said elevator-trough is sup ifli'lted at the rear end of the frame of the mac e and is provided near its lower and upper ends with bearings for the shafts 56 57,

supporting the wheels or drums u on which; the endless carrier 58 of the e evator is? mounted, said endless carrier being e ui ped with a plurality of slats 59. The s a t 57 carries a pinion 60, meshing-with an idle in- I ion 61, with which is connected a sproc etwheel 62, connected by a chain 63 with a s rocket-Wheel 64 upon a suitably-supported s aft 65, carrying a bevel-pinion 66, which meshes with a bevel-pinion 67 upon the driven shaft 38, from which motion is thus transmitted to the carrier of the elevator.

The bottom of the elevator-trough is composed in part of aseries of husking-rolls 68 69, which are mounted in pairs in the sides of the elevator-trough. The shafts 70 of the lower husking-rolls of the several sets are provided at their front ends with sprocket-wheels 71,

an outward direction against the.

and the shafts 72 of the upper husking-rolls of the several sets are in like manner rovided at their rear ends with sprocket-wheels 73. The ends of the several shafts which are unrovided with sprocket-wheels are mounted vslidably in slots 74 in the sides of the trough or casing, and springs 75 are provided Whereby the free ends of the shafts will be forced in the direction of the opposite shafts. By thisconstruction it will be seen that each pair of rolls is mounted yieldably in such a manner as to permit the husks torn from the ears of corn to pass between said rolls and to be discharged upon the ground. Each of the husking-rolls is provided with one or more annular grooves. 76 and with radially-projecting pins 77 engaging the annular groove or grooves of the mate thereof. The sprocketwheels 73 of the upper husking-rolls of the several sets are driven by a chain 78 passing over a sprocket-wheel 79 upon the upper elevator-shaft 57. The sprocket-wheels 71 of the lower husking-rolls of the several sets are driven by a chain 80 assing over a sprocket wheel 81 upon the s aft 65. The huskingrolls of each pair will thus be driven in the pro er direction reversely to each other.

C ain-tighteners 82 and 83 are provided for the purpose of keeping the chains 78 and 80 sufficiently taut to drive the several rolls.

The elevator trough or casing is provided at its upper end with a discharge-spout adapted to dischar e the husked corn into a wagon or receptacle which may be driven alongside of the machine.

The operation of this invention is as follows: The machine is driven along the field in such a manner that the stalks of corn will enter between the corn-guides and between the approximately vertical aprons 32 and 33, down corn being elevated and guided between the carrier-aprons by means of the fingers 20. The snapping-rolls below the carrier-aprons are placed sufficiently low to engage the stalks below the lower ears. As soon as the stalks pass into engagement with the snapping-rolls they will be buckled down by the latter until the ears are encountered, the ears being readily snapped off by the combined action of the snapping-rolls and the carrier-a rons, between which they are held.

The stal s will pass downwardly and out of the way between the snapping-rolls, while the ears are carried in a rearward direction between the aprons 32 and 33 and are deposited' upon the chute 53, whereby they are guided into the trough or casing of the elevator, where they are seized upon by the elevator-buckets and carried in an upward direction over the bottom of the elevator-casing. Presently the ears will be engaged by the husking-rolls, the teeth of which will tear and loosen the husks, which will pass downwardly between the rolls, being thereby stripped and torn from the ears. If the husking operation is not fully performed by the first pair of husking-rolls, it will be unfailingly performed by one of the succeeding sets or pairs of rolls. The husks will pass between the rolls and drop upon the ground, while the ears will be carried upwardly and discharged at the upper end of the elevator.

Having thus described the invention, What is claimed is 1. A pair of stalk-engaging snapping-rolls and a pair of endless aprons supported adj acent to said rolls and cooperating to form an ear-engaging carrier, shafts and drums supporting the endless aprons, and yieldable supporting means for the shafts of one of the aprons.

2. In a machine of the class described, a frame, cross-pieces upon said frame extended laterally to form supporting-brackets, pairs of corn-guides supported upon the said brackets, corn-engaging snapping-rolls supported adjacent to the inner sides of the lower corn-guides, shafts journaled in the lower and upper corn-guides, drums upon said shafts, endless aprons mounted upon said drums and cooperating to constitute an earengaging carrier, and operating means.

3. In a machine of the class described, a frame having cross-pieces extended laterally to form supporting-brackets, corn-guides supported upon said brackets and having recesses in their inner sides, and corn-engaging snapping-rolls disposed in said recesses and having shafts journaled at their front ends in the corn-guides and at their rear ends in a supporting-bracket.

4. In a machine of the class described, a frame having cross-pieces extended laterally to form supporting-brackets, uprights upon said frame, laterally-extended cap-beams, upper corn-guides supported by said capbeams, lower corn-guides supported upon the laterally-extending supporting-brackets, an upright mounted upon the frame and having a yoke supportin the front ends of the upper corn-guides, sta -engaging snapping-rolls supported adjacent to the inner sides of the lower corn-guides, shafts journaled in the lower and upper corn-guides, drums upon said shafts, endless aprons upon said drums cooperating to constitute an endless ear-engaging carrier, and operating means.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in the presence of two witnesses.
